Postinor-2: Your Emergency Contraceptive Option
Postinor-2, also known as P2, is a trusted emergency contraceptive that contains the active ingredient levonorgestrel. Commonly referred to as the “morning-after pill,” it is used exclusively as an emergency measure to prevent pregnancy following unprotected intercourse or sexual activity. This medication should not be used as a regular, long-term contraceptive method.
Mechanism of Action:
Postinor-2 operates in two fundamental ways to reduce the likelihood of pregnancy:
- Pre-Ovulation: If taken before ovulation occurs, it may delay the release of the egg, preventing fertilization.
- Post-Ovulation: If taken after ovulation, it may interfere with the transport of eggs and sperm, reducing the chances of successful fertilization.
Effectiveness and Timing:
The efficacy of Postinor-2 varies with the timing of administration:
- If taken within 24 hours of unprotected intercourse, it offers a 95% chance of preventing pregnancy.
- If taken between 48 to 72 hours (2 to 3 days) after unprotected intercourse, there is a 58% chance of preventing pregnancy.
Its effectiveness beyond 72 hours is uncertain, and it may not be reliably effective if taken more than 72 hours after unprotected intercourse.
Products with similar purposes to Postinor-2, but from different manufacturers, include ECee2.
Directions for Use:
To maximize the effectiveness of Postinor-2, follow these steps:
- Take one 750 μg tablet as soon as possible, ideally within 72 hours of unprotected intercourse.
- Take a second 750 μg tablet 12 hours after the first dose.
- If vomiting occurs within 2 hours of taking a tablet, consult your doctor before considering another dose.
Precautions and Additional Information:
- Postinor-2 does not protect against sexually transmitted diseases (STDs). It is solely designed to prevent unintended pregnancy.
- While your next menstrual period is expected to arrive on time, it may be slightly early or late. If it is more than 1 week late or unusually light, consider taking a pregnancy test.
- If you do not experience a menstrual period after 3 weeks of taking Postinor-2, consult your doctor, as pregnancy needs to be ruled out.
- Do not use Postinor-2 if you have unexplained vaginal bleeding, a history of breast cancer, liver problems, or hypersensitivity to any of its ingredients.
- This medication is not intended for use in pregnant women or those suspected of being pregnant. If there is uncertainty regarding pregnancy, perform a pregnancy test or undergo a pelvic examination before taking Postinor-2.
- In rare cases, if pregnancy occurs after taking Postinor-2, an ectopic pregnancy (a pregnancy outside the uterus) is possible and requires medical attention.
